From an implementation point of view, I'm not sure how this could work unless the new Pebble either has wifi (not out of the question) or there's a mechanism to pair multiple of them to a single phone and clearly mark out which are kid-devices vs primary. As a parent, I totally get you though. Ultimately kids should learn to pay attention and stay on task without the crutch of a digital nag, but it sure would be usef…
I wonder is Apples AirTag networks could be utilised to send data, that would remove any need to have a data/wifi connection and it would also have an inbuilt way to keep tabs on a young child. And for most parents a short message is all that’s needed to send “Running 5 mins late, see you soon” etc.
If I was Apple I'd be extremely cautious about opening that up, though. Not everyone would be excited about the idea of their data plans and bluetooth bandwidth being used up to enable a free texting plan for every kid within twenty meters.
Think of how that would play out at elementary schools, with hundreds of students piggy backing off a handful of teachers' iPhones.
